This repair service is for CPC4(Common Powertrain Controller) modules used in Freightliner, Western Star, Oshkosh, Terex, Pierce trucks and Thomas buses with Detroit Diesel Engines.We repair for the most common issues with CPC4 modules.

  • Dead throttle / Intermittent throttle 
  • CPC reads as a different module (reads as CPC2, TCM, etc.)
  • CPC Hardware Failure Fault Code SPN 609 FMI 12

Our repair also address the following issues when they are associated with communication failure:

  • Check Engine Light is on
  • ABS Light staying on
  • DEF Light staying on
  • Instrument Cluster loses communication

Our repair is designed to address the above issues.

If you are having any problems other than this, please text or call us at 800-547-2049.

Sometimes when the circuitry on your CPC4 fails it also corrupts the programming on the circuit board. Despite that failure, we are able to fully repair this module by reprogramming it to the latest OEM configuration for your vehicle based on your particular VIN.  Your CPC4 will be ready to install and use immediately without additional programming.
